We can see the stars in different groups at times. Many people imagine that different groups of stars together make different shapes in the sky. These imaginary shapes are called constellations.
They are named after ancient people or animals. Constellations look like different animals and people.
Constellations were devised by ancient people so that they can recognize the stars in the sky. The shapes of constellations resemble objects familiar to the people.
A constellation does not have one star. It has a large number of stars. However, we can see only the bright stars in a constellation with our naked eye.
